  * Remove old and non-applied anymore powerpcspe-disable-FPU-code.patch.

    (Closes: #900817)

 -- Gianfranco Costamagna <locutusofborg@debian.org>  Tue, 05 Jun 2018 15:37:46 +0200

ghc (8.4.3-1) experimental; urgency=medium

  * New upstream version.

Description: Disable FPU code on powerpspe

 powerpcspe CPUs don't have an FPU, so the FPU PPC assembly

 code has to be disabled on this architecture.

 See: https://ghc.haskell.org/trac/ghc/ticket/12075
